AIRFBRAKE-PIPE HANGER FR RAILWAY-CARS.

To, all whom t may concern:

Be it known that I, RICHARD YV. BURN Err, a citizen of the United States, residingin Montreal, in the Province of Quebec and Dominion of Canada, have invented a new and useful improvement in Air-Brake-Pipe Hangers for Railway-Cars, of which the following is a specification.

My invention relates to improvements in anchoring devices for attaching air brake pipes or other longitudinal pi pes to cars.

For efficient operation of air brake mechanism of railway ears, it is very important that the longitudinal train pipe should be very securely anchored to the car to prevent strain upon the angle cock couplings and brake mechanism when the cars are subjected 'to severe shocks from bumping and switching and other use.

'lhe object of my invention is to provide an improved construction of air brake or train pipe anchoring device for railway cars, which will be simple in construction and thoroughly eilicient and reliable in opta'ation. l

Bly invention consists in the novel construction of parts and devices and in the novel combinations 'of paris and devices herein shown and described and more particularly specified in the claims.

ln the aecompanying drawing forming a part of this specilication, Figure l is a front elevation of my improved train pipe anchor, the train pipe being shown in section. Fig. 2 is a longitudinal section on line 2 2 of Fig. -l and Fig. Il is a detail elevation, looking from the line rof Fig. l.

ln the drawing, l represents the needle beam or other portion of a railway car frame and 2 the air brake pipe extending through an opening -i in the needle beam or frame member and which is to be anchored thereto.

My improved anchor comprises an anchor plate or disk 4r secured by rivets 5 to the needle beam or frame member l, and provided with an integral hub or sleeve portion 4 which is furnished with one or more, preferably two, longitudinally extendingkey slots (3, having inclined or wedge faces 7 to receive the wedge keys each ol which has a straight, horizontal face J for engage- Specification of Letters Patent.

ment with the train pipe and an inclined 0r wedge face 10 for engagement with the inclined or wedge face 7 of the key slot in the-anchor disk or plate 4. The opening 3 in the needle beam or frame member 1 is made large enough to receive the train pipe 2 and also the wedge keys 8. The opening l1 in the anchor plate or disk 4 is preferably made only slightly larger than the train pipe or just large enough to admit of the easy and convenient insertion of the train pipe through the anchor plate. rlhe Wedge keys 8 have at their straight or longitudinal faces an extended bearing against the Y trainpipe and at their Wedge or inclined faces l() against the anchor serve to very securely hold and lock the train pipe against longitudinal'movement in respectto't'he car frame, The ends 12 of the wedge keys 8 may be bent at an angle to lock them in position.

1. A train pipe anchor for railway cars, comprising an anchor plate secured to the car frame and provided with an integral extended hub furnished with a Wedge faced slot-and a wedge key having a straight, unbroken face for engagement with the train pipe, said face being in engagement with the pipe throughout its entire length, and an inclined face for engagement with the inclined face of the key slot in the anchor said key extending beyond both ends of the hub and having its inner end adapted to be bent to prevent the same from accidentally falling out.

2. A train pipe anchor for railway cars, comprising an anchor plate secured to the frame and provided with an integral extended hub furnished with a pair of wedgefaced slots, and a Wedge key in each of said slots, each key having a face for engage ment with a pipe passing' through said 'nnb and an inclined face for engagement with the inclined face of one of said slots in the. anchor plate,

said keys extending beyond plot? ends of the hub, substantially as speci- Ruil-IARD VEBB BURNETT. lVitncsses:
